As we know, there is a neighboring forum that is starting to get busy for some reason, and we can teleport the account there. So what happens if someone sells their account on a neighboring forum? Maybe it hasn't happened yet, but someday it might happen when the neighbor forum becomes bigger than it is now. (I mean selling teleport accounts from bitcointalk accounts)
We all know the forum you're referring to, this has to do with their own rule over there, if a teleported account got sold there, then that's at their own disposal to determine if doing such is against the rules or not, then what may affect the same account is if they share same information which seems to be a pirate copy of each other, what I mean here is if you plagiarize to the other forum, your account here and there may be unsafe, tagged or banned, I don't how vast the scam and spam burster are there, but the likes of Gazetabitcoin and others there could help a little in fishing out those involved from the other forum.
